\n" ); document.write( "\n" ); document.write( "        The form \" four times older than \" is never used in Math problem written in English,\r
\n" ); document.write( "\n" ); document.write( "        since this form is ambiguous in English.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "        The form \" four times as old as \" should be used in this problem in this context.\r
\n" ); document.write( "

\r\n" );
document.write( "Amelia is 16; hence Theodore is 16/4 = 4.\r\n" );

document.write( "    16+x = 2*(4+x).\r\n" );
